Potters for peace designed a low cost water filter using clay and colloidal silver. Is meant to be incredibly effective, given the cost. See: http://www.worldchanging.com/archives/000112.html
The charity IDE were supporting this idea in Nepal but seem to have stopped. Haven't contacted the guy below given by IDE so don't know what these filters now are or what they cost. Feel free to explore!
Note from IDE:
IDE Nepal was involved in CS filter promotion but now we are not working in this field. We have handed over our technology to one entrepreneur in Kathmandu who is doing his business. The filter is not ceramic, plastic container is used and good for filtering ecoli and coliform. For detail you can contact
